M: Hello, Prof. Diana, you wanted to see me?
W: Oh, yes, Frank. Thanks for coming.
M: That’s all right. I’m quite nervous. Jack sounds weird when he noticed me this.
W: You shouldn’t be. It’s about your work as a teaching assistant. I’ve just read your evaluations, the ones the students filled out toward the end of the semester.
M: Yes...? Were they terrible?
W: No, not at all.
M: Well, how were they?
W: Would you like to take a look? Out of a possible score of five, you got a four point eight. That’s very high, Frank.
M: Well, what a pleasant surprise.
W:(9)When we see such a high score, we generally try to keep the teaching assistant on a little longer and perhaps even ask them to cover more classes. What do you say, Frank? Would you like this?
M:(10)I sure would, but I don’t know if I can. Next fall will be my last semester of course work for my master’s and I’ll be very busy doing research on my thesis.(10)Could I have a few days to think about it?
W: Certainly, I wouldn’t want you to fall behind in your course work,(11)but 1 do think you should consider getting more experience in the classroom. You seem to have a real gift.
M: Thanks for your praise, Professor.
W: Let me know by the beginning of next week, will you?
M: Sure thing. I’ll drop by again on Monday or Tuesday.
